Ensure hostmibd is not in use
Description
The hostmibd daemon is a dpi2 sub-agent which manages a number of MIB variables which may be required if the server runs SNMP. The specific MIB variables which are managed by hostmibd are defined by RFC 2790. Details relating to these MIBS can be found in: https://www.ibm.com/docs/en/aix/7.2?topic=h-hostmibd-daemon Audit: the hostmibd start line in /etc/rc.tcpip must be commented out and the hostmibd subsystem must not be active.
How it is checked
Audit method: Shell command
command -v lssrc >/dev/null 2>&1 || exit 1; [ -r /etc/rc.tcpip ] || exit 1; out=$( { grep -E "^[[:blank:]]*start[[:blank:]]+/usr/(sbin|lib)/hostmibd([[:blank:]]|$)" /etc/rc.tcpip; lssrc -s hostmibd | awk 'NR>1 && $NF=="active"' ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20- Expected output
compliant
How it is fixed
Fix method: Guidance or infrastructure patch
Run the following command to remove the software: # /usr/sbin/installp -u bos.net.tcp.snmpd bos.net.tcp.server - OR - - IF - the bos.net.tcp.snmpd fileset is required as a dependency: Run the following script to stop and disable hostmibd #!/usr/bin/ksh DAEMONS="hostmibd" for l_daemon in $DAEMONS; do /usr/sbin/chrctcp -d $l_daemon /usr/bin/stopsrc -s $l_daemon done
